macOS is great – I really like it a lot – but one thing it doesn’t handle all that great is … network shares.

In this day and age a little weird to still see this, especially from a company like Apple. We are more network connected than ever before – at home, in school and at work. We have network shares on our computers, want to access company network shares, or have a dedicated file server or NAS (Network Attached Storage) to store our information or make our backups.

Unfortunately, it is still cumbersome under macOS X to connect to those “shares” (also known as mounted network “Volumes“).

In Finder, a server doesn’t always appear right away, we need to go through a list of shares on a given “server”, get confused if we need SMB, CIFS, FTP, SSH, WebDAV, NFS or AFP, and I’m not even mentioning the need to enter a username and password on protected shares.

For this reason I created ConnectMeNow – initially just for personal use.
But the arrival of the 64 bit requirement, mandatory signed applications, and notarization requirements, and Catalina issues, my original old version was simply outdated.

So after months of work, I’d like to present ConnectMeNow v3, which hopefully makes working with shares easier for you as well.

In this article, I’ll show you how you can login to SSH (Secure Shell) more secure, without not using a password, by using SSH-keys.

SSH allows several types of services to connect securely (encrypted and such) to be used, but the most common one is Shell (command line) access.
It is mostly used as a much more secure replacement for Telnet, rlogin, rsh etc.

Quite often, when starting to use SSH, most users will use a username and password to get SSH access, but this not the most secure method.
More secure, and easier to use, is by using so called SSH-keys, and in this article I’ll try to explain as simple as possible how this works and how to get started with this.

We have just released ApplePi-Baker v2.2.0.
This version was released with macOS Catalina in mind.

The first release of macOS Catalina (10.15) came with some serious problems for applications like ApplePi-Baker and the likes (Etcher etc).
The “Full Disk Access” security setting seemed to have a bug, preventing reliable access to external disks.

After Apple released its first update (10.15.1) this bug seems to be resolved in a way.
Accessing external disks still comes with a few challenges, so when a disk is being selected, ApplePi-Baker will verify  if “Full Disk Access” works.
If not, a notification and explanation will be shown how to enable “Full Disk Access” for ApplePi-Baker.

Additionally, a small bug (leaving a temp file behind after a backup or restore in ~/tmp) has been resolved.
If partition resizing was used when restoring an image, the resized IMG will still remain, saving you the time to restore the same image again.

In this article, I’ll show you the steps to create macOS install Media …

As most Mac users will know; each new macOS version comes with a few challenges. For some it’s nothing, for other it’s a disaster.

Catalina is one of the latter, a disaster for quite few amongst us, due to changed security rules and the lack of support of 32 bit applications.
Some of my favorite tools simply no longer work, and as a developer this makes me nervous when considering switching to the latest and greatest.

For this purpose I always create a virtual machine in VMWare Fusion, running the macOS version that I ran before the update.
This comes with challenges though, since Apple, in their infinite wisdom, does not simply provide macOS install media (eg. a DMG or ISO file) so you can install another version of macOS. We have to create our own.

Note: Here I describe how to create macOS install media, either as a bootable USB stick to do a fully clean macOS install for your Mac, or a DMG file, for example to setup a virtual machine.

As a hobby developer, when testing dark theme vs light theme under MacOS X, I have those moments where I have to switch back and forth between both themes quite often.
Going into the System Preferences to toggle theme, choosing the Appearance option, and then selecting the desired theme, does indeed work, but I wanted just a “one click” theme toggle.

To help myself with that, I created a small application that does exactly this: it toggles to “the other” theme, with just a simple click.
So when Dark Theme is active, it switches to the Light (Aqua) Theme. If however the Light Theme is active, it switches to Dark Theme.

The application is super simple, and has no interface. Just start the App and it changes theme and then closes itself.
Normally, this App would just sit in your Applications directory, with the optional shortcut in your Dock or even on the Touch Bar (if your Mac has one).

I’m very excited to announce that ApplePi-Baker now supports shrinking and expanding of Ext2, Ext3 or Ext4 Linux partitions on a Mac!!
This is something I wasn’t able to do before and is commonly seen as a challenge on a Mac (since MacOS does not support these Linux File Systems).

This update can only shrink or expand Linux partitions on a MBR partitioned disks (very common format used for the Raspberry Pi).

Keep in mind: I’ve done quite a lot of successful tests, but by lack of beta testers, I’m still marking it as experimental.

During backup, if the option has been enabled, ApplePi-Baker will locate a Linux partition and if found shrink it to it’s minimal size, and update the IMG file and it’s partition table (the source will not be affected). This will result in a much more compact IMG file, and offers a restore to a device of a different capacity.

On Restore, this same option will expand that Linux partition to the maximum available size on the target disk.
Obviously, the target device needs to be able to accommodate at least the minimum size of the IMG file.

Since quite a bit needs to be done (find partition, check file system integrity, resize partition, etc), this will naturally slow down the backup and restore process, but it will help restoring to different sized target disks/SD-card.

Not only that, version 2.1.0 is much faster than 2.0.0 – I’ve seen speed increases up to 300% during backup.

You can find the latest version of ApplePi-Baker in the original article (please place comments there).

ApplePi-Baker has become well known amongst Raspberry Pi users, with a Mac running macOS, to backup and restore SD-cards. Users do not just use ApplePi-Baker for this purpose anymore – I have seen users use it for backup and restore of pretty much anything not Raspberry Pi related.

Late 2013, I created ApplePi-Baker for my own use – I just got tired of looking up the proper command-line statements.
This way, ApplePi-Baker became my personal frontend for command-line tools like “dd“, “diskutil“, “mount” etc.

Over time, the use of command-line tools came with some problems; thanks Apple for changing command-line tool output with every new version of macOS. Besides that, having to enter your “sudo” password each time was a pain as well, and came with the occasional problems for a small group of users, so that had to go as well.

About 2 years ago I decided to rebuild ApplePi-Baker from scratch, no longer using any of the command-line tools. This came with quite a few challenges, especially since Apple increased security for macOS, not allowing me to do certain things straight from my program (see also SMJobBless: Elevated Privileges in Lazarus Pascal). I’m not even mentioning the drama when it comes to supporting the different compression formats, signing applications, and 64-bit requirements.

Almost 2 years later, I proudly present ApplePi-Baker v2. – special thanks to Jeff and Mark for testing!

UPDATE: ApplePi-Baker now also support shrinking and expanding of Linux partitions!

As some of you know, I created ApplePi-Baker a while ago, and with a new version I wanted to get away from using command-line tools like “dd” and “diskutil“. To do this the right way I needed to know how to use SMJobBless, in order to get root access, a.k.a. elevated privileges, privileged helper tool, etc.

Back in the day, we could do this pretty easy in our application, simply by using opening, reading and writing data from/to disks as “files”, with relatively simple code in our applications. These days seem to be gone …

With all kinds of malware trying to “hack” us, companies like Apple and Microsoft keep making it increasingly more difficult to actually get admin (root) access straight from our application (not to mention the seemingly cumbersome signing of applications). Which is all good, just too bad that the now majority of the time I spend on developing an application involves adapting to these limitations, instead of doing the creative thinking towards what the application really is for.

Apple has created a poorly documented mechanism for this, referred to as “SMJobBless” or “Privileged Helper“, and focusses heavily on Objective C and Swift – neither of these I like, let alone working with XCode (yuk!) – I really prefer working in Pascal, and specifically in an awesome IDE provided by Lazarus Pascal.

So in this article, I’m documenting my own findings to get this working with Lazarus Pascal – which took a lot of work and testing.

Keep in mind – I’m definitely not an expert on this topic, and I tried to include as much of what I found out as possible. It appears no-one has done this with Lazarus Pascal yet, so please bear with me, and definitely feel free to post improvements and/or suggestions. I’m sure there may be better ways and I’m always open to improving things, including myself.

Apple has done a pretty good job with the Dock in MacOS. There is just one thing that I do not like though; the way it stacks icons when you add a folder to your Dock.

A smart guy from Japan (2007 – Yasushi Chida) actually came with a neat idea for that, by introducing “buckets” (or better said: Stack Overlays) placed over the folders in your Dock. All that without the need to install any extra applications!
Unfortunately, his website at Yahoo!/Geocities has been gone for quite a while now.

The few steps you have to take can be a little bit challenging for MacOS beginners (even though it is pretty easy – as usual; once you know how it works). So in the article I’ll show you how to use buckets (a.k.a. Stack Overlays) in your MacOS Dock. This seems to work as of MacOS X Leopard and still works in Mojave (and I do expect this to work in future versions as well).

Some of you may be familiar with the problem … no sleep button on your keyboard.

You have a really nice Mac, but you’re using a Windows keyboard since there is no MacOS keyboard that you really like.
I’m using a keyboard from Havit (you can find it here).

One of the things I hate about this setup is that I have no key or key-shortcut to put my computer to sleep.
When you look at the Apple reference, you’ll only find keys that cannot be found on your Windows keyboard, like the Eject key, or the Power key.

So in this article, I’ll show you, without the use of special software, how I have created a keyboard shortcut to put my Mac Pro to sleep, using a Windows keyboard.

Waking up devices that are network connected, can be done with the so called “Wake On LAN” feature provided by certain devices (like for example a NAS, FileServer, or even a PC). A while back I created a simple application for this – miniWOL – keeping in mind that the user may not be too familiar with all the configuration details (see: previous miniWOL versions).

I wanted just a simple menu in the System Tray (Windows: next to the clock, usually the lower-right corner of your screen) or Menubar (MacOS X – top of your screen, Linux often at the bottom of your screen). Well, after a bit of searching I could not find anything suitable or to my liking and I decided to just write something myself.

The old miniWOL has been good so far, and plenty folks seem to have a good use for it privately and professionally. However, Apple had to change a few things (moving to 64 bit, using Cocoa instead of Carbon, and the need to sign and notarize applications – I suspect Microsoft will probably follow soon) so while revamping the Mac version, I revamped the Windows version as well, and added a 64-bit Linux version as well (by request).

I’m not sure about other developers, but I occasionally like to use my own custom font for my Lazarus Pascal applications. Typically I do this so I have access to better icons and symbols available in my application, instead of semi blurry bitmap icons. If you use this the right way, your icons and symbols will look much better and will scale really great.

Usually, I use a TTF font for this which I generate at IcoMoon.
IcoMoon is an awesome website where you can compile your own TTF font (or SVG or PNG images of symbols) for use with your website (Tweaking4All uses it as well) or … in your applications.

Since there are plenty examples out there how to do this in Lazarus Pascal for Windows, here an article that shows you how to do this in Lazarus Pascal under macOS.

Previous miniWOL versions proved that just reading the specifications of Wake on LAN and testing with your own equipment is not going to result in a 100% perfect application, as it seems that certain machines prefer to see a broadcast over the network instead of a specific IP address.

In this new version, you can still retrieve the Mac Address based on IP address, and use a broadcast mask (255.255.255.255 is the default). This should help with certain setups like Synology devices.

This update applies to Windows and MacOS versions of miniWOL.

Note: I have just uploaded a revised v1.2 (Friday Dec. 9 2016) which fixes sending a WOL when miniWOL starts for those servers that have been tagged as such.

ApplePi-Baker has been updated again – this time fixing a small bug for macOS Sierra users (beta 2 tested).

The disk/SD card size was not displaying. This has been fixed in 1.9.4.

Please report any issues you might run into when running MacOS Sierra, at the original ApplePi-Baker article where you can also download the latest version.

Special thanks to Barry for reporting .

ConnectMeNow, a small application for Mac OS X to quickly mount network shares, has been updated to version 1.7.9 – yes i’ts an odd version number, but this has to do with a lot of testing by Steffen and others.

Some of the changes include:

Support for separator lines in the menu, buttons to move items up and down in the list, support to save the config file anywhere you’d like (they can even be shared with other computers, for example through DropBox etc.), option to backup/restore your config file, “Execute AutoMount” function, menubar fix for macOS Sierra, fixed bug which would reset the number or shares to zero (= loosing all settings!), standard preferences are now stored per Apple Guidelines, and a minor bug in WOL has been fixed.

For  download of the latest version, please read the original article (Quickly connect Network shares on a Mac with ConnectMeNow), where you can also ask questions or report issues. Or … find the application on our Downloads Page.
